Hi folks!
We're hunting down a mystery where two of our big university relays are having troubles reaching the Tor directory authorities: https://gitlab.torproject.org/tpo/network-health/analysis/-/issues/86
Can you check to see if your relay is in a similar situation?
In particular, the situation to look for is "Tor process is still running fine from your perspective, but, relay-search (https://atlas.torproject.org/) says you are no longer running."
If your relay is in this situation, the next step is to check your Tor logs, try to rule out other issues like firewall rules on your side, and then (if you're able) to start exploring traceroutes to the directory authority IP addresses vs other addresses. If you need more direct help, we can help you debug or answer other questions on #tor-relays on IRC.
Thanks, --Roger
